In a first, South Korean children are being transported to and from school in a classic, American-made yellow bus.

And it was built right here in New York.

Warwick-based Trans Tech — which employs people who live all over the Lower Hudson Valley — struck a deal earlier this year to provide at least 100 yellow school buses annually to Seoul-based J.S. Alliance. Trans Tech did not disclose the length of the contract.

Other, more practical, changes included reducing the height of the bus steps, plus exterior light changes to conform to South Korean laws and converting the speedometer and other gauges to the metric system and the Korean language.

The retractable stop sign, too, had to be changed to Korean.

Trans Tech President John Phraner called the sale a "historic moment."

“We could not be more appreciative of our partnership with J.S. Alliance LTD, Mr. Bae and his entire team,” he said. “We are looking forward to manufacturing many more Trans Tech school buses for South Korea.”

The bus is currently the only American-made school bus approved for use in South Korea.

“Our main objective is to help make South Korea’s school transportation system as safe as possible and to use Trans Tech school buses to accomplish that goal,” said Bae. “Trans Tech makes a great bus and it perfectly meets the needs of our country.”
